Hi, thanks for your comment. You don't need to play through the entire game again to discover the other ending. When you finish the game and start a new one, it will take you back to the last chapter where you can increase your husband or boss points to unlock the ending you're missing. As for the whole game lasting one hour, I don't think that's possible, since just the prologue (chapters 1 and 2) takes approximately one hour to see all the NSFW scenes. Anyway, I'll look into ways to improve the gameplay experience. Have a great day!
